This communications app is a great tool for portable amateur radio SSTV operation. Just connect your Android phone or tablet to an HF radio (or even set it next to the radio’s speaker), tune on to an SSTV frequency, and watch the pictures scroll onto the screen. DroidSSTV supports the ham radio modes Scottie 1, Scottie 2, Scottie DX, Martin 1, and Martin 2 at this time.
